Abstract (en)
[origin: US2009002148A1] A sensor monitoring system is described that identifies inaccurate or degraded sensor data and corresponding sensors. The system analyzes a plurality of sensors to determine reliable sensors and isolate or reinterpret unreliable sensor data. An analysis component analyzes a traffic representation that varies as context varies and determines the probability that current sensor data is invalid. Learning and reasoning are performed from a case library of sensor failure data to build predictive models of sensor health that can provide inferences about the output of sensors. Resulting inferences about sensor reliability can be employed in base-level inferences and predictions about traffic flow.
